Theres a regulator type thing on the front of the plenum, has a wire that goes to it, with im pretty sure it has to do with the fuel. I broke the wire but car runs the same. what is it,what will it do without it? lmk something thanks!

 

That's the fuel regulator, and I believe the wire is just for sensing fuel temp? It probably won't make much difference at all, unless there is an extreme change in fuel temp. I'm sure someone will educate me on this if I'm wrong.

 

would an aftermaket help on a na?
